VALVE-FITTING FOR SODA-WATER APPABLTQ'S.

Specification of Letters Patent. P t nted Sept. 14, 1909.

Application filed August 4, 1908. 'seriel No. 448,888.

exactdescription as will enable any one I D ing and discharging ofthecylinder without frequent removal of the valve-fitting being skilled inthe art'to-which it appertains to inake and use the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

The principal objects of my presentin -vention are to provide a sodawater fountain valvefitting having but a single hand-valve controllingthe passage through which the water and charging gas are introduced andthe charged water withdrawn, and which fitting at the same time permitsboth chargremoving the fitting, thereby avoiding the necasity of.removing the valve fitting to charge the cylinder, as has heretoforebeen the general practice, the drawback to this the-rupturing of thejoint between the blocktin lining of the fountain and the bung oripe-connection to which the valve-fitting is connected. D

With these and other ob ects 1n View, my

invention consists in the various novel and peculiar arrangements andcombinations of the several diiferent parts of the apparatus, all ashereinafter fully set forth and then pointedoutin the claims. I

I have illustrated types of my invention in the. accompanying drawings.wherein Figure 1 is a longitudinal vertical sectional view of a sodawater fountain or cylinder shown as. having my improved fittingappliedthere'to. Figs. 2 and 3 show, respectively, enlarged wrews ofvertical central sections of the fitting shown detached, the sectionsbeing taken at right angles to each other, in these two views. Flg. 4,1sa view of a central longitudinal section of a-modified form of thefitting. i V

Referring to the drawings, in which like numbers of rcferencel dislgnatelike ptarts l at 1 is a sore ountain cons1s 1ng iii riij liiidr made ofsuitable metal to withstand the internal pressure from the conindex 1and the linin 2 and to which the lining is secured in on er to form agas and water tight joint. The exterior of the outer "end of the nozzleis provided wit-ha screw thread ,on which works a nut 6 for drawing thenozzle upwardly and securely locking it in place in the cylinder. Thefitting comprises a valve casing 7 provided with a valve chamber 8 inwhich works a valve 9 which is made of suitable soft material and seatsitself on the annular ridge 10 which is rounded as indicated to revent,cutting the soft material of the va re. The ynlve is provided with astem ll which has a screwthread 12 working in a correspondingscrewthread upon the interior of the removable part 12 which at itsinner end has an external thread 13 fitting a corresponding interniilthread in the tubular extension 14. A washer 15 is placed between thepart 12 and tlie'end of the tubtdar extension 14 to make a gas and watertight joint and the outer end of theJ'alve-stem 11 passes through aremovable cap 16 which has an interior screwth'read l7 fitting acorresponding exterior' thread on the outer end of the removable part-]2". and a soft washer or packing 18 1s placed within the cap, asindicated, to make.

the joint gas and water tight. The valve casing has a branch 19. throughwhich ex-' lends a passage 20 counnunicating with the lower end of saidbranch and with the valvechamber 8, the valve-seat 10 being at the innerend of this passage 20. The exterior. of

the branch 19 is screw-threaded at '21 to fit the internal screw-threadof the pipe-section or nozzle 4,'and it is also provided with a, lateralflange 22 in the under face of which is sunk a soft annular washer 23which bears down against the upper end of the pipe-seetion 4 when thefitting is screwed down hard and thus provides a gas and water tightjoint between the fitting and the ipe-sect-ion 4.

To'the lower end of the brane 19 of the fit-- ting is soldered orsuitably secured the tube 24 which is used for both filling the cylinderand witlulrawing the contents. and this pipe extendsto near the botttimof the cylinder,

as indicated in Fig. l. The fitting '7 is also 5 provided with anotherlateral Branch or extension through which extends a passageliiCOlHlTilllllCiltlllg with the valve-chambers so that this valvecontrols the communic:

tion between the passage 20 and the passage :56. This branch part :35 isprovided with an external screw-thread 27 by means of which it may becoupled with any device for withdrawing the contents of the cylinder orwith the pipe for charging the water within the cylinder with carbonicacid gas; Ifit beattempted to fill the cylinder with'liquid, by

opening the valfia J and forcing the liquid in, it will be found thatthe necessary quantity of liquid cannot thus be forced in without somemeans of venting or permitting a quantity of the contained air toescape. for

this reason it has been the custom to remove the fitting in order toobtain the large opening provided through the pipe-section a and to thenfill the cylinder by a pipe or hose inserted in the nozzle and to thedesired height,

though, of course, these cylinders are not entirel y filled with liquidas some considerable space must be left for the compressed gas withwhich the water is charged.

In my present invention, I provide an air vent which comprises a duct orpassage extending through the fitting and connnuuieating at its lowerend with the short tube 130 which runs down parallel with the main tube24 and is soldered thereto at 31. he outer end of the air duct 2!)extends through a boss or'projection 32 which is provided with a handvalve comprising a cap haviag an interior screw-thread 34 working onacorresponding screw-thread on the boss or extension 32, and this cap isprovided with a lateral opening 36. The air vent 29 opens upon the outerend of the boss or extension 32 which forms practically a valveseat forthe valve 37 which is made of soft material and this closes by screwingdown the cap tight upon the boss, as shown in Fig. *1. This cap isprovided on its exterior m) with flat faces 38 like those of a nut forreceiving a wrench to turn down the valve hard to L'll) t it and toloosen the same when it is desired to vent the cylinder, the vent :21)being in free counuunication with the .55 lateral perforation 36 in thecap when the cap is partly unscrewed. as shown in Figs.

2 and 3. In order to prevent the cap from 3 becmfllng detached, 1provide the same with an inwardly projecting pin 35) which takes so intoan oblique slot 40 in the side of the boss 32, and this pin and slotserve to retain the cap from detac luuent, as will be readily understoodfrom the drawings.

'In Fig. 4, I show another form of the ii tin, it lacing. substantiallythe same as thatdescribed in the other figures with the enception thatinstead of the air vent 29 opening through a boss upon the upperend ofthe fitting, it opens into a socket 41 in the side of the fitting whichsocket or cavity is provided with an internal thread for receiving theexterior screw-thread {'2 on a plug 43, and this plug is provided withan L-shaped passage l4 extending longitudinally into the same and thenlaterally so as [0 open on one side of the plug aswell as the end, asindi- 'cated in Fig. 4. This plug is provided with a lateral flange 45beneath which is a washer at; for bearing upon the outer end of thesocketed part 47. This washer 40 and the SQ end of the socketed part 47form practically a valve and its seat, so that the vent may be closed byscrewing the plug in tight, in which case the vent 44 opening upon theside of the plug .will be completely covered and 35 closed air and watertight. By unscrewing this plug partially or entirely the vent may beopened. l-he outer end of this plug is provided with flat faces forrecei ing a wrench like the part 38 of the valve cap 33 in the otherconstruction.

The upper end of the fitting T in Fig. -'l provided with a roundedprojection 50 which like the end of the valve cap 33 in the otherfigure, may he used as a handle in rolling the cylinder 1 on its lowerend from place to place, the same as a barrel is rolled by a person inmoving it from one point to another.

It will now he understood that with this I venting arrangement,thecylinder may be filled with water to the required height without.removing the fitting at all, so that the same becomes practically apermanent fixture of the soda fountain or cylinder. In

charging these fountains, it is the practice to only partially fill thevessel in order to leave above the water therein a space for thecharging or carbonating' gas which is also injected into the fountain.The length of 11!).

the vent-pipe 30 depends somewhatupon the amount of liquid with whichthe cylinder is to be charged so that where a lessquantity of water isto be used the vent-pipe 30. is made longer than when the cylinder is tobe 1 charged with'more water. Accordingly if desired. this ent-pipe 30may be varied in length depending upon whether the cylinder is tocontain a less or greater amount of \vatcr. By attaching a pipe, such as-18. to the lateral branch the empty cylinder may have the water forcedtherein to fill it, by opening the valve 9 by me'ans of the handle '49secured to the end of the valve stem 11 at the same time opening thevalve of the vent passage 29. Under this condition, as the water isforced in the cylinder, it begins to compress the air above the water,as the water enters much more rapidly than the air can escape throughsuch a small passage as 29. When the water rises in the filling ooration to a point above the lower end of t 1c vent pipe30.1ll0fi1'8n'8l1l8 of the air above the water will be' 'm to force thwater up through the vent pipe and this wi '1 continue until a quantityof \vater'is forced out of the outer end of the air vent so as to beseen by the operator. and this indicates that it is time to shut oh" thesupply of water as the same has then reached the required height in thecylinder. .In this way the venting arrangenwnt also serves as a gage forinforming the operator as to the quantity of water in the cylinder andletting him know when to stop the filling process. Ordinarily, theproper height ofthe water is ascertained in filling these cylinders withthe fitting removed by the operator inserting a'sticlt or rod in thenozzle 4 and withdraw-' ing it to note the height of the water in the cyinder.

It will, of course. be understood that the outlet or eduction port ofthe air vent may be located upon any part- 0 the valve casing. l hav ngherewith shown two such loca tions both of which provide very convenientarrangements. Of course, any well-known form of hand valve may be'nsedto control the venting part.
